TIME-RESOLVED PHOTOLUMINESCENCE STUDY OF EXCITON LOCALIZATION IN CD1-XMNXTE
The authors have measured time-resolved photoluminescence from the dilute magnetic semiconductor Cd1-xMnxTe for x up to 0.3. For x=0.09 they observe exciton localisation both by neutral acceptors and by alloy potential fluctuations; for higher x-values they observe localisation in alloy potential fl...

description | The authors have measured time-resolved photoluminescence from the dilute magnetic semiconductor Cd1-xMnxTe for x up to 0.3. For x=0.09 they observe exciton localisation both by neutral acceptors and by alloy potential fluctuations; for higher x-values they observe localisation in alloy potential fluctuations to be dominant. In the latter case localisation occurs on a timescale of <20 ps. Subsequent rapid transfer to lower-energy localised states, with a characteristic time of about 150 ps, is interpreted as being due in part to magnetic polaron effects. © 1986 The Institute of Physics. |
